The expression 12g gives the number of kilometers a car can travel using g liters of gasoline. How far can this car travel on 5 1/2 liters of gasoline?

Answers

Answer:

66 km

Step-by-step explanation:

Given that

Number of km's traveled by a car using g liters of gasoline = 12g

Number of gallons of gas required to travel 12g kilometers = g

We have to find

How far this car can travel using $5 (1)/(2)$ or 5.5 liters of gasoline = x= ?

Now we can find this by substituting g= $5 (1)/(2)$ in the the above equation representing number of kilometers traveled by the car.

Number of km's traveled by a car using $5 (1)/(2)$ liters of gasoline = 12 ( $5 (1)/(2)$ )

x = 12 (5.5)

x= 66 km

So, the car travels 66km in 5.5 liters of gasoline

Substitute in 5 1/2 for g in the expression : 12g=12(5 1/2)=66

So, this car can go 66 kilometers on 5 1/2 liters of gasoline.

Tommy has a pet monkey. Every day, his monkey eats 4 apples in the morning. The monkey also eats two bananas for every banana that Tommy eats.Write an equation to describe this situation where x is the number of bananas Tommy eats and y is the total number of pieces of fruit the monkey eats.

Answers

If you would like to write an equation to describe the following situation, you can do this like this:

4 apples in the morning ... 4
x ... the number of bananas Tommy eats
2 bananas for every banana that Tommy eats ... 2 * x
y ... the total number of pieces of fruit the monkey eats

The equation would be as follows: y = 4 + 2 * x.

A sweater is on sale for $33. This is 75% of the original price. Find the original price?

Answers

75% of the original price is $33.

33 = 75% * x

33 = 75/100 * x

33 = 3/4 * x

x = 33 * 4/3

x = 11 * 4

x = 44

The original price of the sweater was $44.

It was $44
I just plugged in numbers I did 44*0.75 and it gave me 33.
